I guess (I haven't actually "fixed" the situation yet) that the file conflict is resolved, but something is different then normal because SONAME bumps and new binary names normally don't cause apt to "keep back" the old binaries. I don't totally understand, I'm very much guessing it related to a simultaneous SONAME bump in one of the reverse dependencies. Just reporting in case others see something worse.
